'''Longlisted for the CILIP Carnegie Medal 2013'''
Twelve-year-old Jess is dealing with a lot. Her beloved Aunt Edie has just died. Her mother is expecting twins - but these new babies will be Jess's half-brothers and will complete Jess's mother's marriage to her stepfather. But will they complete Jess's family? Will they even survive? Because the twins are conjoined. And in 70% of separations, only one twin lives. And if this weren't enough in the way of trials and tribulations, Jess's best friend Zoe is moving towards a relationship with a boy. Does this mean she will leave Jess behind?
If ''The Flask'' appeals, we can also recommend [[A Monster Calls by Patrick Ness]], a beautiful story of coming to terms with the loss of a parent from an idea by the late - and much missed - Siobhan Dowd and given wonderful life by Patrick Ness in words and Jim Kay in pictures. Lovers of language would also enjoy [[Hate That Cat by Sharon Creech]], a gorgeous novel in free verse and a perfect introduction to poetry for anyone, young or old alike.
